<p>By default, packages fully using GNU <code>gettext</code>, internally,
are installed in such a way as to allow translation of
messages.  At <em>configuration</em> time, those packages should
automatically detect whether the underlying host system already provides
the GNU <code>gettext</code> functions.  If not,
the GNU <code>gettext</code> library should be automatically prepared
and used.  Installers may use special options at configuration
time for changing this behavior.  The command &lsquo;<samp>./configure
--with-included-gettext</samp>&rsquo; bypasses system <code>gettext</code> to
use the included GNU <code>gettext</code> instead,
while &lsquo;<samp>./configure --disable-nls</samp>&rsquo;
produces programs totally unable to translate messages.
</p>
<a name="IDX1108"></a>
<p>Internationalized packages have usually many &lsquo;<tt><var>ll</var>.po</tt>&rsquo;
files.  Unless
translations are disabled, all those available are installed together
with the package.  However, the environment variable <code>LINGUAS</code>
may be set, prior to configuration, to limit the installed set.
<code>LINGUAS</code> should then contain a space separated list of two-letter
codes, stating which languages are allowed.
